TECHNICAL FIELD

This present disclosure relates to the field of alfalfa (Medicago sativa) breeding, specifically relating to alfalfa varieties with low or reduced lignin content.

BACKGROUND

Alfalfa (Medicago sativa) has often been referred to as the “Queen of Forages” because it is an excellent source of protein and digestible fiber, and because of its wide adaptation. Alfalfa has a high mineral content and contains at least 10 different vitamins and is an important source of vitamin A. It is grown for hay, pasture and silage, and is valued highly as a livestock feed. Increasing alfalfa fiber digestibility by decreasing lignin content is known to improve forage quality, ration formulation flexibility, and enhance feed value. Doing so while not adversely affecting yield and without having to introduce transgenes to develop stable, high yielding cultivars with low or reduced lignin content has long been a goal of alfalfa breeders.

SUMMARY

The present invention is directed to an alfalfa variety that has at least about 5.0% less lignin content as a percent of dry matter, compared to a control alfalfa variety grown under the same field growing conditions. The alfalfa variety may have at least about 5.0% to at least about 25.0% less total lignin content. The alfalfa variety may have about 5.0% to about 25% less acid detergent lignin content. The alfalfa variety may have at least about 6.0% to at least about 10.0% less acid detergent lignin content. The lignin content may be measured about 21 days after clipping, about 22 days after clipping, about 28 days after clipping, about 29 days after clipping, about 35 days after clipping, or about 42 days after clipping. The lignin content may be measured in the lower stems or in the whole plant of the alfalfa plant. The alfalfa variety may have at least about 5.0% to about 25.0% more total digestible nutrient, 5.0% to about 25.0% more relative forage quality, 5.0% to about 25.0% more relative forage value, or 5.0% to about 25.0% more milk per ton of dry mass compared to the commercial alfalfa variety grown under the same field growing conditions. The total digestible nutrient may be measured as in vitro total dry matter digestibility, neutral detergent fiber digestibility, or total tract neutral detergent fiber digestibility. The total digestibility nutrient may be measured about 21 days after clipping, about 22 days after clipping, about 28 days after clipping, about 29 days after clipping, about 35 days after clipping, or about 42 days after clipping. The control alfalfa variety may be a commercial alfalfa variety.

For the recitation of numeric ranges herein, each intervening number there between with the same degree of precision is explicitly contemplated. For example, for the range of 6-9, the numbers 7 and 8 are contemplated in addition to 6 and 9, and for the range 6.0-7.0, the number 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, and 7.0 are explicitly contemplated.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In case of conflict, the present document, including definitions, will control. Preferred methods and materials are described below, although methods and materials similar or equivalent to those described herein can be used in practice or testing of the present invention. All publications, patent applications, patents and other references mentioned herein are incorporated by reference in their entirety. The materials, methods, and examples disclosed herein are illustrative only and not intended to be limiting.

Terms used in the descriptions and tables that follow are defined as follows:

Acid Detergent Fiber (“ADF”). Acid detergent fiber approximates the amount of cellulose fiber and ash present in a feed. Forages with high ADF values are less digestible than forages with low ADF values and, therefore, provide fewer nutrients to the animal through digestion. Because of this relationship, ADF serves as an estimate of digestibility and can be used by nutritionists to predict the energy that will be available from a forage.

Acid Detergent Lignin (“ADL”). Acid detergent lignin is the lignin in the residue determined following extraction with acid detergent. ADL is an estimate of lignin content. Lignin is an indigestible component of forage fiber (NDF) that is believed to limit the extent to which forage fiber can be digested by ruminant animals.

Crude Protein (“CP”). Crude Protein (“CP”) is determined in part by measuring the total nitrogen concentration of a forage. This technique measures not only the nitrogen present in true proteins, but also that present in non-protein forms such as ammonia, urea and nitrate. Because most of the non-protein forms of nitrogen are converted to true protein by the rumen microorganisms, CP is considered by nutritionists to provide an accurate measure of the protein that will be available to ruminant animals from a given forage.

DM. DM is the abbreviation for Dietary Dry Matter and used to calculate yield.

Digestible Neutral Detergent Fiber (“dNDF”). Digestible Neutral Detergent Fiber is the digestible fraction expressed as % of DM.

Enhance feed value and Relative Feed Value (“RFV”). Enhance feed value refers to the forage quality, such as fiber content, digestibility, and available carbohydrate resources available to livestock. Enhanced feed value or alfalfa quality is determined by the Relative Feed Value (RFV) expressed as a percentage of alfalfa at 100% bloom and is used as a predictor of feed value in the field. Components that effect feed value are acid detergent lignin concentration and G lignin and neutral detergent fiber digestibility. The measurement of these feed value components is an aspect of the invention.

Dyn Kd. Dyn Kd refers to the rate of fiber digestion or the digestibility rate.

Fall dormancy (FD). Most alfalfa plants go dormant in the fall in preparation for winter. The onset of dormancy is triggered by a combination of day length and temperature and is genotype dependent. Fall dormancy scores measure the dormancy response of alfalfa genotypes by quantifying how early dormancy is triggered. The standard fall dormancy test requires that plants are cut off in early September with plant height measured in mid-October. Early fall dormant types show very little growth after the September clipping, later fall dormant type demonstrate substantial growth. Alfalfa is classified into fall dormancy groups or classes numbered 1 through 11, where fall dormancy group 1 is very early fall dormant suited for cold climates and fall dormancy group 11 is very non-dormant and suited for very hot climates in which the plant would grow throughout the winter months. FD 1 is considered Very Dormant, FD 2 and FD3 are considered Dormant, FD 4, FD 5 and FD 6 are considered Moderately Dormant, FD7 and FD 8 are considered Non-Dormant, and FD 9, FD 10 and FD 11 are considered Very-Non-Dormant.

Forage yield. Forage yield is measured by harvesting herbage for part of or the entire life of the stand.

In Vitro True Digestibility (“IVTD”). In Vitro True Digestibility is a measurement of digestibility utilizing actual rumen microorganisms.

In Vitro True Dry Matter Digestibility (“IVTDMD”). In Vitro True Dry Matter Digestibility measures the digestibility of the entire forage plant by incubating samples of the plant in rumen fluid taken from a cow, then boiling the incubated samples in neutral detergent to ensure that all non-fiber portions of the sample are removed. This procedure estimates how much of the total dry matter in a forage plant is actually digestible by the cow.

Milk Per Acre (“MA”) and Milk Per Ton (“MT”). Milk Per Ton is an estimate of forage quality and milk production that could be supported by a given forage when fed as part of a total mixed ration. Milk per ton (lb/ton) is primarily driven by starch content, starch digestibility, and NDF digestibility. The equation for calculating milk per ton uses Neutral-Detergent Fiber (“NDF”) and Acid-Detergent Fiber (“ADF”) to calculate total energy intake possible from the forage. After subtracting the amount of energy required for daily maintenance of the cow, the quantity of milk that could be produced from the remaining energy is calculated. The ratio of milk produced to forage consumed is then reported in the units of pounds of milk produced per ton of forage consumed. Milk per ton is useful because it characterizes forage quality in two terms that a dairy farmer is familiar with: pounds of milk and tons of forage. “Milk Per Acre” is determined by combining milk per ton and dry matter yield per acre (lb/acre). Milk per acre is calculated by multiplying milk per ton times dry matter yield per acre. These terms are widely used to estimate the economic value of a forage.

Neutral-Detergent Fiber (“NDF”). Neutral-Detergent Fiber represents the total amount of fiber present in the alfalfa. “aNDF” refers to amylase-treated neutral detergent fiber.

“Neutral Detergent Fiber Digestibility” (NDFD). Neutral Detergent Fiber Digestibility (NDFD) refers to the content of forage is a measure of the digestibility of a forage fiber as % of NDF, and can be measured in vitro and predicted using Near Infrared Reflectance Spectroscopy (NIRS). NDFD is the digestible fraction expressed as % of NDF. The higher the NDFD value the more digestible the forage. NDFD represents the indigestible and slowly digestible components in plant cell wall (cellulose, hemicellulose, lignin (units=% of dry matter)). dNDF may be used to calculate NDFD.

Persistence. The ability of the cultivar to last over a minimum of two years. This measurement is documented in the visual percent stand remaining at the time of observation.

Relative Forage Quality (“RFQ”). Relative Forage Quality (“RFQ”) is a numeric value that estimates the energy content of forage for total digestible nutrients as recommended by the National Research Council. Values are assigned to forages based upon the actual fiber digestibility (NDFD) and Total Digestible Nutrients (TDN). By combining these two relationships, an estimate of how the forage will perform in animal rations is predicted. Relative forage quality has been accepted in many areas as a means of estimating forage feeding value and is commonly used in determining the price of alfalfa at tested hay auctions or for on farm use.

Synthetic variety (“SYN”). SYN variety is developed by intercrossing a number of genotypes with specific favorable characteristics and/or overall general favorable qualities. SYN variety can be developed by using clones, inbreds, open pollinated varieties, and/or individual heterozygous plants.

TA. TA is the abbreviation for Tons per Acre and is used to calculate yield.

Total Digestible Nutrients. Total Digestible Nutrients (“TDN”) is an estimate of the energy content of a feedstuff based on its relative proportions of fiber, fat, carbohydrate, crude protein, and ash. Because it is expensive to measure each of these components, TDN is usually estimated from ADF or IVTD. TDN may overestimate the energy content of low quality forages and thus may not accurately reflect the nutritional value of all forage samples.

Total Tract NDF Digestibility (“TTNDFD”). Total Tract NDF Digestibility (“TTNDFD”) is a tool that combines feed (feed fiber—potentially digestible NDF rate of fiber digestion) and cow (fiber digestion—rate of passage) factors to measure energy from fiber. It is a calculation that uses several time points of NDFD, for example, after 24, 30, or 48 hours, combined with the rate of fiber digestion, the rate of fiber passage and also indigestible fiber, therefore giving a better picture of fiber digestibility as a whole. The calculation is calibrated to a cow producing 85 pounds of milk. A 2-3 unit change in ration TTNDFD corresponds to a one pound change in milk yield.

Weighted mean. Weighted mean is similar to an arithmetic mean where instead of each of the data points contributing equally to the final average, some data points contribute more than others.

2. ALFALFA VARIETIES WITH LOW OR REDUCED LIGNIN

The present disclosure relates to alfalfa varieties having low or reduced lignin content that does not result from introducing one or more transgenes. Lignin is an insoluble polymer which occurs in the secondary thickening of plant cell walls and is primarily responsible for the rigidity of plant stems. Although lignin is essential for vascular function in plants, and may be involved in disease resistance in cereals, there is much interest in producing plants with reduced lignin content.

The digestibility of forage grasses by cattle decreases with increasing lignin content. Lignin concentration is an important measurable factor limiting the in vitro digestibility of other constituents including cellulose, hemicellulose, and neutral detergent fiber. Small increases (approximately 1%) in lignin content can result in relatively large decreases (approximately 7%) in digestibility of plant dry matter. For example, an increase in one percentage unit NDFD results in a 0.37-pound increase in forage dry matter intake per day (lb/d), and a 0.55 lb/d increase in 4% fat corrected milk (FCM) yield. Cows fed forages with greater NDFD are able to obtain more total energy and nutritive value from the forages. As a result, the energy requirements can be fulfilled with less grain provided in the diet. Lower NDFD in forage legumes is most often related to the maturity of the forage plant, which is accompanied by an increase in lignin concentrations and associated with an increase in cellulose fibers.

Fall dormancy influences stand persistence, adaptation, and performance. Yield and quality are related to fall dormancy and maturity. Non-dormant varieties (FD 7-9) mature faster and typically yield more compared to dormant varieties, yet dormant varieties have more quality and lower lignin. Non-dormant alfalfa varieties (higher fall dormancy groups) typically have higher lignin content compared to more dormant alfalfa varieties (lower fall dormancy groups). The disclosed alfalfa varieties have low or reduced lignin content compared to control alfalfa varieties in the same fall dormancy group and/or control alfalfa varieties that are more dormant.

10. USES OF LOW-LIGNIN ALFALFA PLANT

The present invention contemplates using the low-lignin alfalfa plant, or part thereof, or an alfalfa plant having the physiological and morphological characteristics of the low-lignin alfalfa plant, as a source of breeding material for developing or producing an alfalfa plant in an alfalfa breeding program using plant breeding techniques. Plant breeding techniques useful in the developing or producing alfalfa plants include, but are not limited to, single seed descent, modified single seed descent, recurrent selection, reselection, mass selection, bulk selection, backcrossing, pedigree breeding, mutation breeding, restriction fragment length polymorphism enhanced selection, genetic marker enhanced selection, and transformation. Plant breeding techniques are known to the art and have been described in the literature.

Methods are provided for introducing or introgres sing a desired trait into alfalfa low-lignin. High yield alfalfa plants are inter-mated to produce the next generation of seed. Seed from the first cycle, is re-selected, and inter-mated to produce the next generation of high yield plants. This process of selection and inter-mating is conducted until desired level of yield is achieved. Plants are produced that have the desired trait and all the physiological and morphological characteristics of alfalfa variety low-lignin.

As used herein, the term “plant” includes, but is not limited to, plant cells, plant protoplasts, plant cell tissue cultures from which alfalfa plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts thereof. “Plant part” includes, but is not limited to, embryos, pollen (pollen grains), ovules, seeds, flowers, pods, leaves, roots, root tips, anthers, and the like.

One may obtain alfalfa plants according to the present invention by directly growing the seed low-lignin or by any other means. An alfalfa plant having all of the physiological and morphological characteristics of low-lignin can be obtained by any suitable methods, including, but not limited to, regenerating plants or plant parts from tissue culture or cuttings. The scope of the present invention is not limited by the method by which the plant is obtained.

The present invention contemplates genetic transformation of the low-lignin alfalfa plants. Polynucleotides may be introduced into a plant cell of alfalfa low-lignin to produce a transgenic low-lignin alfalfa plant. At least one, two, three, four, five, six, seven, eight, nine or ten polynucleotides may be introduced. As used herein, “introduced into a plant” with respect to polynucleotides encompasses the delivery of a polynucleotide into a plant, plant tissue, or plant cell using any suitable polynucleotide delivery method. Methods suitable for introducing polynucleotides into a plant useful in the practice of the present invention are well known in the art and include, but are not limited to, freeze-thaw method, microparticle bombardment, direct DNA uptake, whisker-mediated transformation, electroporation, sonication, microinjection, plant virus-mediated, and Agrobacterium-mediated transfer to the plant. Any suitable Agrobacterium strain, vector, or vector system for transforming the plant may be employed according to the present invention.

In some embodiments, a plant may be regenerated or grown from the plant, plant tissue or plant cell. Any suitable methods for regenerating or growing a plant from a plant cell or plant tissue may be used, such as, without limitation, tissue culture or regeneration from protoplasts. Suitably, plants may be regenerated by growing transformed plant cells on callus induction media, shoot induction media and/or root induction media. The regenerated plants have substantially all the morphological and physiological characteristics of the alfalfa variety named low-lignin that are described in the attached tables.

In certain embodiments, the polynucleotides to be introduced into the plant are operably linked to a promoter sequence and may be provided as a construct. As used herein, a polynucleotide is “operably linked” when it is placed into a functional relationship with a second polynucleotide sequence. For instance, a promoter is operably linked to a coding sequence if the promoter is connected to the coding sequence such that it may effect transcription of the coding sequence. In various embodiments, the polynucleotides may be operably linked to at least one, at least two, at least three, at least four, at least five, or at least ten promoters.

Promoters that may be used include, but are not limited to, constitutive, inducible, temporally-regulated, developmentally regulated, chemically regulated, tissue-preferred and tissue-specific promoters. Suitably, the promoter causes sufficient expression in the plant to produce the phenotypes described herein. Suitable promoters include, without limitation, the 35S promoter of the cauliflower mosaic virus, ubiquitin, tCUP cryptic constitutive promoter, the Rsyn7 promoter, pathogen-inducible promoters, the maize In2-2 promoter, the tobacco PR-1a promoter, glucocorticoid-inducible promoters, and tetracycline-inducible and tetracycline-repressible promoters.

Polynucleotides may also be provided in a vector. Suitable vectors include plasmids and virus-derived vectors. Vectors known in the art that are suitable for transformation into plants, cloning, and protein expression may be used.

The present invention relates to transformed versions of the claimed alfalfa variety with low-lignin as well as hybrid combinations thereof.

Polynucleotides that may be used include, but are not limited to, those that alter an agronomic trait such as conferring resistance to insects, disease, herbicides, or abiotic stress, or by altering fatty acid metabolism, carbohydrate metabolism, starch metabolism, amino acid metabolism, phosphorus metabolism, antioxidant metabolism, male sterility, site specific DNA integration, plant growth, forage yield and flowering. Examples of such traits are described in U.S. Pat. No. 6,652,195, the entire disclosure of which is herein incorporated by reference.

Polynucleotides that may be introduced include those that confer resistance to insects or disease, including, without limitation, coding sequences for plant disease resistance such as tomato Cf-9 for resistance to Cladosporium falvum, tomato Pto for resistance to Pseudomonas syringae pv. Tomato, Arabidopsis RSP2 for resistance to Pseudomonas syringae, Bacillus thuringiensis (bt) protein, insect-specific hormones or pheromones and variants and mimetics, such as an ecdysteroid and juvenile hormones. Examples are described in U.S. Pat. Nos. 5,188,960, 5,689,052, and 5,880,275, the entire disclosures of which are each herein incorporated by reference. A plant resistant to a disease is one that is more resistant to a pathogen as compared to the wild type plant.

The present invention has multiple aspects, illustrated by the following non-limiting examples.

11. EXAMPLES

The foregoing may be better understood by reference to the following examples, which are presented for purposes of illustration and are not intended to limit the scope of the invention.

Example 1 Methods and Materials

The year the alfalfa plants were planted is considered “Year 0.” Plants harvested in the same calendar year of planting are considered “Year 0” harvested plants; plants harvested in the next calendar year after planting are considered “Year 1” harvested plants; plants harvested two calendar years after planting are considered “Year 2” harvested plants; plants harvested three calendar years after planting are considered “Year 3” harvested plants; and plants harvested four calendar years after planting are considered “Year 4” harvested plants.

Dormant Forage Yield Trials:

Experimental design was randomized complete block with 3 replications. Trials were seeded at 20 lbs per acres. The plot size used was 4′ wide by 15′ long (7 rows per plot with 6 inch spacing or outside row to row was 36″). Forage was harvested at 28, 35, and/or 42 days depending on the trial. Plots were harvested at approximately 10 cm height. Yield is reported in tons/acre. Plots were fertilized using 400 lbs/ac annually of 1-2-20-12s (applied after each cutting to achieve the 400 lbs annually). Insects (potato leaf hoppers (Empoasca fabae)) were controlled as needed using Baythroid insecticide at rate 2 oz/acre. Weeds were controlled during year of establishment using post emergence application Raptor herbicide at 4-6 oz/acre rate.

Forage Quality Sampling:

The alfalfa plants were analyzed at various stages of maturity from 28 to 42 days or Bud Stage to Bloom stage, including Stages 1, 2, and 3, where each stage is a specific number of days after prior cut/harvest where applicable: Stage 1—Early (about 21 days); Stage 2—Medium (about 28 days); and Stage 3—Late (about 35 days). Forage digestibility typically decreases with higher stages, whereas the total yield typically increases with higher stages. Samples were taken by cutting stems at 10 cm height from soil surface using an 18″ section of 2×4″ board to ensure uniform cutting height. Samples were placed in perforated plastic flats in forced air oven at 60° C. or 140° F. for 48 hrs. Samples were ground through 4 mm screen using a Wiley mill or chop grinder. Samples were then blended using wearing blended to ensure ground leaves and stems were well mixed. Samples were then ground through 1 mm screen using an Udy mill or abrasion grinder and place in a 120 ml specimen sample cups. Samples were the then tumbled in a drum to ensure no particle size separation prior to scanning. Samples were allowed to equilibrate to 22-24° C. prior to scanning in ring cup on a Foss 5000 NIR Spectrometer. Forage quality estimates were predicted using the NIRS Forage and Feed Testing Consortium Alfalfa Breeders equation and/or Rock River Labs TTDNDF equation.

Semi- and Non-Dormant Forage Yield Trials.

The plot size used was 3′ wide by 16′ long (5 rows per plot on 6 inch spacing or outside row to row was 24″). The cutting height was 1.75 inches from soil surface with a 2×4″ board laying flat. Different fertility, insect, and weed control program were used. Flood irrigation was performed between cuttings. In Woodland Calif., samples were cute at 1.75 inches (4.4 cm—the depth if a 2×4 board laid on the soil next to the rows to be sampled). The plots were 16 feet in length. 4 replications were performed.

Chemical Applications:

A pre-plant herbicide Balan DF and Eptam 7E was incorporated with a rototiller followed by a ring roller for semi compact soil bed. The targeted insects were armyworms, alfalfa caterpillar, lygus, aphids, and thrips. Warrior II (1.9 oz per ac) and Beseige (10 oz per ac) were used for control. For weed control after establishment, Raptor (6 oz per ac), Pursuit (6 oz per ac) and Velpar (5 pts per ac) were used. The fields were flood irrigated 2 to 3 times per between cuttings (up to 7 cuttings per season).

Example 2 Forage Yield—CW096043

The total forage yield, as dry matter in tons per acre, and stand of CW096043 was determined over four years and compared to commercial fall dormancy group 6 varieties (Table 1). Stand refers to the final stand percentage and is a measure of persistence. Tests were conducted at Woodland, Calif. The forage quality was measured with 5, 6, or 7 cuts per year for a total of 24 cuts.

Example 3 Forage Quality—CW096043

The forage quality of CW096043 at Stages 1 (about 21-22 days after clipping), 2 (about 28-29 days after clipping), and 3 (about 35 days after clipping) was compared to various commercially available alfalfa varieties using the methods described in Example 1. The forage quality data, as an average of 3 cuts, are presented in Tables 2-4 for Year 3 harvested plants and Tables 5-7 for Year 4 harvested plants. In Tables 2-4, CW096043 was compared to fall dormancy group 6 alfalfa varieties P56S82 and PGI 608, fall dormancy group 7 alfalfa varieties HybriForce 700 and PGI 709, fall dormancy group 8 alfalfa varieties P58N57 and PGI 801, fall dormancy group 9 alfalfa varieties Mecca III and PGI 909, and fall dormancy group 10 alfalfa varieties CW 1010 and Fertilac 10. In Tables 5-7, CW096043 was compared to fall dormancy group 6 alfalfa varieties P56S82, PGI 608, and WL440, fall dormancy group 7 alfalfa varieties HybriForce 700, PGI 709, and SW7410, fall dormancy group 9 alfalfa varieties Mecca III and PGI 909, and fall dormancy group 10 alfalfa varieties CW 1010, Fertilac 10, and Sedona.
